There were three configurations for the PowerMac G5. A total of 9 computer-controlled fans were used in the G5, which amazingly was one of the quietest PowerMacs in years. The case was divided into 4 discreet 'thermal zones' each with its own cooling system.

The PowerPC 970 was a higher-power and higher-temperature chip than its 74xx predecessors, and a considerable amount of engineering went into the cooling system of the PowerMac G5. This represented a more than six-fold improvement over the previous PowerMac G4 model.

Most impressive of all was the front-side bus speed, which was increased to half of the processor speed-up to 1.0 GHz. It included a variety of motherboard enhancements, including PCI-X slots, and 8X AGP slot, a Serial-ATA bus, and up to 8 GB of RAM. It featured either a single 1.6 or 1.8 GHz processor, or dual 2.0 GHz processors. Housed in an innovative new Aluminum enclosure, the PowerMac G5 was the first 64-bit consumer-level desktop computer ever sold. Apple and IBM had worked closely together for nearly a year of the PowerPC 970 Processor (publicly referred to as the G5), and the 64-bit PowerMac G5 represented a huge leap forward in both processor and machine design. Motorola had been chronically delayed for both processor design and shipment, and was at least a year away from its fifth-generation PowerPC CPU. In an important move, Apple decided to break with Motorola, and used an IBM-designed processor. RAM modules for all models must be installed in matched pairs.Īnnounced in June 2003, the PowerMac G5 was Apple's long-awaited fifth generation PowerPC-based machine. The Dual 2.0 GHz model shipped with a 64 MB ATI Radeon 9600 graphics card. The 1.8 and Dual 2.0 GHz models shipped with 512 MB of RAM. The 1.8 GHz model had a maximum power consumption of 430 watts. It shipped with 256 MB of RAM, and an 80 GB hard drive, and had a maximum power consumption of 420 watts. The 1.6 GHz model had four PC2700 333 MHz RAM slots for a maximum of 4 GB of RAM, and three 33 MHz, 64-bit PCI slots.
